Diagram shows helicopter H flying towards an island P When the helicopter is 100 m above sea level, the pilot sees a man fishing from boat Q. Given the angles of depression of the island P and boat Q from H are 22° and 61.5° respectively.

Calculate the distance, in M, of PQ

Please help me to explain :(

193.21 m

Step-by-step explanation:

make a vertical line down from the helicopter that is 100m

tan 61.5 = 100/x       x = 54.3 (distance from the point directly below helicopter                                                                  to boat)

tan 22 = 100/x          x = 247.51 (distance from the point directly below helicopter to the island

247.51 - 54.3 = 193.21 (distance from boat to island)

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
